Answer 1

Answer:

18/5

Step-by-step explanation:

given quadratic equation is 2px^2+6x+5=0;

given that quadratic eqn has equal roots.

let it be X

we know that sum of the roots is -b/a

X+X=-6/2p;

2X =-6/2p;

X =-3/p;

and product if roots is c/a

X * X = 5/2p;

X^2=5/2p;

(-3/p)^2=5/2p;

(9/p^2)=(5/2p);

9/p =5/2;

p=18/5.
